AUTOMOBILE-HORN.

Specification of Letters'latent.

Patented Dec. 21, 1915.

in the art to which it appertains to make and use the same.

This invention relates to automobile horns, which are more particularlyadapted for use upon conveyances, tor boats and the like, though'I donot desire to limit my invention to use as signal devices employedinthis service only.

My invention is directed to the same general purposes as that disclosedin the application of \Villiam IV. Dean May 1st, 1911 and in my Patent#1,020,7 68, Mar. 19, 1912, my, object being to improve upon the devicesdisclosed in order to produce a more simple article which can be morecheaply and conveniently manufactured and which will more effectivelyproduce the results desired with less interference with the signaling.

Other objects of my invention and the invention itself will be betterunderstood from the detailed description of the device illustrated.

' modification shown in Figure 1 shows a section of one form of mydevice taken through the line II of Fig. 2. Fig. 2 is a front elevationof the Fig. 1. Figs. 3 and 4 illustrate a modification of the inventionas illustrated in Figs. 1 and 2.

Referring first to the form illustrated in Figs. 1 and 2, I show aplurality of parts 1 and 2 which form the walls of a chamber, and here Ihave only shown two parts, though it will be obvious that any number maybe employed. The part 2 constitutes the rear of the chamber, and in theform shown, is illustrated as a cup-like member, having a bottom 3 andside walls 4. The

edges of the walls may be folded outward as shown at 5, preferablysubstantiallyat right angles to the walls 4. The part 1 constitutes thefront of the chamber, and may be compared to the top of the cup, sinceit is intended to fit over that part to close the top such asautomobiles, mo- 1 #624,330, filed;

thereof. The front should be perforated as shown at 7, to permit theescape of sound waves, and may have a boss 8 formed around the edge ofthe opening, to which a. resonator 9 may be attached.

The edge of the part 1 may be folded over the end of the part 5 as shownat 10. In the form shown in Figs. 1 and 2, a channel 11 is left betweenthe part 10 and the edge of the annular member 5. A sonorous member,such as a diaphragm 12 is clamped between two of the parts forming thewalls of the chamber, and is here shown as clamped between the annularmember 5 and the front. This member may be a vibratile diaphragm withits edges clamped, as described.

The center portion of the part 1 is prefer ably elevated, as shown at13, to permit the diaphragm to vibrate without striking this part. Inorder to prevent the accumulation, in this portion of the chamber, offoreign matter, such as dirt, dust and water which enter the opening 7,I provide draft channels, through which the air rushes, drawing thismatter through the chamber, and out without permitting it even to remainin contact with the diaphragm, where it would interfere with the soundproduced.

In the form illustrated in Figs. 1 and 2, I have created a suitablenumber of arms 1 1 to the elevated part 13. These parts form passageways or channels, as shown at 15 in the front and between the diaphragmand the wall of the front part 1, and communicating with the channel 11,furnish a clear passage way for the air and foreign matter through theinstrument.

The front may be formed, as illustrated, by punching it from a singlepiece of metal, and is fastened to-therear by suitable fastening means,such as screws 16.

In the form illustrated in Figs. 3 and 4:,

20 to form a niche in the edge thereof, which communicates with thepassage 15, the part 10 being here folded over to fit snugly against theend of the annular member 5. The diaphragm may also be cut away to forma niche 21 in the edge thereof to correspond with the niche, 20 in thepart 5, thus creating a passage as shown in Fig. 3 for the purpisesdescribed in connection with Figs. 1 an 2.

.a chamber, one o shown for the purpose of illustrating the invention,andnot for limiting me to the details thereof.

I claim a 1. In an automobile horn, the combination of a plurality ofparts vformin the walls of a chamber, one of said parts be around theedge, such-annular member being cut away to form a niche in its edge, adiaphragm clamped around its'edge between the annular member and thefront wall of the chamber, the edge of the front Wall of thechamber'being folded over the edge of the annularmember, said front wallbeing formed to create a passage between the front wall and thediaphragm, such passagejconnecting the chamber with the niche in theannular member, whereby foreign matter may escape from the diaphragm,and means to operate said diaphragm.

2. In an automobile horn, the combination of a plurality of arts formingthe walls of f said parts having a niche cut in the same, and a secondof said parts being formed to create a passage between the interior ofthe chamber and said niche to' permit the escape of foreign matter fromthe ing cup-shaped and having an annular member" 1 chamber and asonorous member and means to operate the same in the chamber.

3. In an automobile horn, the combination of a plurality ofparts formingthe walls of achamber, one of said parts being cupshaped and having itsedge foldedoutward substantially at right angles to the walls of thecup-shaped member, such folded outward part having a niche cut therein,such parts being formed to create a passage way from the interior of thechamber, through such niche, to permit the escape of foreign matter fromthe chamber, a sonorous memher and means to operate said member.

4. In an automoblle horn, the comblnation of a plurality of partsforming the walls of a chamber, one of said parts being cup-shaped andhaving its edge folded outward substantiall at right-angles to the wallsof the cup-s aped member, such folded outward edge being cut away toform a niche in the edge thereof, a second part forming a cover for saidcup having 1ts edge folded over the edge of the cup-shaped member, adiaphragm clamped between said members, such parts being formed tocreate a passage way between the diaphragm and the walls of the chambercommunicating at one end with the interior of the chamber and the nicheto permit the escape of foreign matter from the chamber, and means to0perate said diaphragm.

In testimony whereof, I have signed m'y name in the presence of twowitnesses.
